AVIATOBS GOGGLES.

Specification of Letters Patent.

Patented Jan. 22, 1918.

To all whom it may concern:

Be it known that I, CHARLES J, TROPPMAN, of the city of Chicago, countyof Cook, and State of Illinois, have invented certain Improvements inAviators Goggles, of which the following is a specification.

My present invention relates to goggles or eye-protectors, and moreparticularly to devices of this character that areadapted to be worn byaviators and others engaged in like pursuits where it is essential tocombine dependability and compactness in articles of wearing apparel andfor use in making flights. l

Among the divers objects of my invention is the provision in go gles oreye-protectors of a simple and depen able hinge connection between theoppositely disposed eye-cu s and lenses, which will afford a requisiteegree of flexibility to the structure to facilitate the adjustment ofthe device to the face of the wearer, and will also provide facilitiesfor the removal and insertion of new lenses, and will further permit ofthe folding of the lenses, face to face, when not in use in whichposition the lenses will be protected from breakage by the flexibleeye-cups. It

is also an Ob ect to provide goggles that are so constructed. that theedges 0 the eye-cups thereof will conform to the contour of that portionof the wearefis face surrounding the eye-sockets, and are capable ofbeing readily folded into "compact form in order to be packed in a relatvely small s ace when not in use; and a further object .o my inventionis the provision of a goggle in which the lens-supporting structure isprovided with means for securing)the lens in position, located adjacentthe ridge so that the mounting is capable of adjustment at the inneredges of each lens in-orde'r to permit the accommodation of lenses ofvarying dimensions.

I prefer to attain the divers objects of my invention by substantiallythe "means disclosed in the accompanying drawings that form a -part ofthis specification, wherein;- Figure 1 is a front elevation of a pair ofgog les or eye-protectors embodying my inven ion.

1 Fig. 2 is a to edge view thereof, showing the same folde together incompact form.

Fig. 3 is an enlarged detail of the hinge portion of the goggleassembled.

. Fig. 4 is a view similar to Fig. 3, showing the hinge and itsassociated members prior to assembly.

Fig. 5 is'an enlarged section taken on line 55 of Fig. 1, illustratingthe manner of assembling the flexible eye-cup, the lens and the lens'rim.

Fig. 6 is a detail view similar to Fig. 3, of a slightly modified-construction of bin e.

Fig. 7 is a view similar to Fig. 4 o the modification illustrated inFig. 6.

Fig. 8 is a detail view in perspective of the eye cup frame.

In the drawings I have employed similar reference characters todesignate the same parts throughout the several views.

The og les comprise separate lenses 10, 10, pro era ly of the lobe orleaf type, that are each fitted into rims 11, of material such asthinmetal or any other suitable substance, that surround and conform tothe' contour of the respective lenses. The ends of each rim arepreferably bent laterally toward each other to provide long and shortmembers 12, 12, so that their end edges come adjacent each other whenthe same are assembled, the upper member 12, being 'considerably shorterthan the lower member.

Suitable upper and lower knuckles 13, are formed upon the sides of eachend member 12 in vertical alinement with each other and correspondingknuckles 13, 13 are formed upon the facing edges of end members 12" allof which register, in order that one of the pintles 14 of the hinge maybe passed throughsaid knuckles and through two double hinge links 15 andthereby lock each lens in its respective rim, as well as to secure themembers of the hinge together in the desired manner. The links 15 are ofsubstantially a figure 8 shape in transverse section, so that eachpintle 14 passes through one of he tubes of each; and, in order toadjust t e rim to the lenses and to securely hold the parts of the hingetogether, I prefer to screw-thread the lower portion of each pintle andtap the same into the lowermost of the knuckles 13, that is internallythreaded to receive the same. The rims are stamped substantiallyM-shaped in cross-section, as shown, in order that the lenses may beconveniently held in one of the grooves thus formed and the collapsibleeye-cups are carried by the opposite grooves in said rim, aswill nowmore fully appear. These cups are formed of a strip of thin silk gauze16, which, after the pattern has been cut, is folded centrally uponitself and one loop 17 of a wire frame is disposed in the fold thusmade, and the same snapped into its proper groove in its respective rim.A second loop 18 is made to complete the wire frame above me tioned,both of said loops (17 and- 18) con orming in plan to the contours ofthe lenses, the loop 17 being flat when viewed.

from its edge and the loop 18 being-shaped so as to conform to thedepressions and raised portions of the face of the wearer adjacent theeye-socket. Suitable resilient means such as forming the loops 17 and 18of the same, or of a continuous, piece of spring wire as shown in Fig.8, so as to connect the necks or reduced. portions of these frames inorder that the frames 18 may be moved toward the lens rims when thegoggles are folded together and compressed into a compact area, as shownin Fig. 2, and eyelets 16 ar fastened into the gauze to pro videventilation for the eye-cups.

The two free edges of the gauze 16 are adapted to surround the movableloop 18 of the frame after the wire of the latter has been wrapped witha suitable filler 19 that forms a pad thereon, after which a soft tape20 of plush, velvet or the like, is stitched around the same to secureit in place. I prefer, in. order to" provide a soft cushion against thewearers face, and to insure the exclusion of dust, smoke, or air rushingunder the edge of frame 18, to attach a strip of chenille 21, or othermaterial having long nap, such as fur or the like, to the outer surfaceof the tape 20, thereby completing the eye-cup of the goggle andmaking'a soft cushion against the wearers face.

It willbe observed that, whenever the lenses are folded together in themanner shown in Fig. 2, the same will be protected against accidentaldamage by the movable frames and by the padding upon said frames that.are thendisposed upon both sides of the folded goggle.

In Figs. 6 and 7, I have illustrated a slightly modified form of hingestructure wherein the end portions of the rims terminate insubstantially equal length lateral members 30, that are each providedwith a .single knuckle 31 adjacent their bent portions, the upper andlower knuckle of each rim alining with each other. pair of knuckles oneach rim are spaced apart a distance sufficient to accommodate betweenthem single elongated hinge link 32 also'of figure 8 cross-section andwhich is adapted to be assembled by the insertion of the pintles 33,through said knuckies and said links, in substantially the same manneras the other form is assembled. By these structures the lenses areretained in vertical plane of the intles and are prevented from flexingthere rom.

In both forms it will be observed the ends of the rims are held togetherby the hinge pintles and it will also be noted that the interior edgesof the lenses shown are much more irregular than the outer edges. Bybringing together and joining the rims at their inner edges by the hingepintles, differences of dimensions of lenses upon their inner edges canbe easily accommodated, when a replacement of lenses is necessary.

A difference of dimension of the outer freely.

curving edges of-the lenses requires no special facilities toaccommodate as the flexible metal of the rims easily shapes itself tothe easily curving edge of that portion of the lens.
